The paths by which people journey toward happiness lie in part through the world about them and in part through the experience of their souls. On the one hand, there is the happiness which comes from wealth, honor, the enjoyment of life, from health, culture, science, or art; and, on the other hand, there is the happiness which is to be found in a good conscience, in virtue, work, philanthropy, religion, devotion to great ideas and great deeds.
